DNMG 150412 NS9530 – Tungaloy indexable insert for turning, finishing-grade cermet

The DNMG 150412 NS9530 is an ISO-standard rhombic indexable insert designed for finishing operations in turning, optimised for continuous cuts and small depths of cut.

• Finishing-grade uncoated cermet NS9530
• ISO-standard DNMG shape, 55° cutting angle
• 1.2 mm corner radius for fine surface finish
• Double-sided insert with central hole

Optimised finishing performance with reduced cutting forces

The NS9530 grade is an uncoated cermet formulated for finishing steel, offering a sharp cutting edge that lowers cutting forces and improves surface quality. Cermet combines ceramic hardness with metallic toughness; this means the cutting edge remains stable during continuous cuts, while wear is predictable and even. With a 1.2 mm corner radius, the insert is suited to produce a refined surface without excessive tool pressure, making it appropriate for tight tolerance external and internal turning where a premium finish is required.

Reliable fit and secure clamping for consistent results

Built to ISO dimensions, the DNMG geometry guarantees predictable compatibility with appropriate holders and boring bars. The 55° rhombic form and central cylindrical hole ensure positive location and stable clamping, while the plate thickness of 4.76 mm supports rigidity during machining. Because compatibility depends on form, clearance angle, tolerance class, fastening and size, selecting the matching holder and torque for the clamping screw is essential; when correctly mounted, vibration is minimised and repeatable part quality is achieved.

Productive finishing cycles with easy indexing and chip control

The double-sided design provides two usable cutting edges per face, enabling economical edge changes and steady process behaviour. The integrated double-sided chipbreaker is optimised for continuous cutting conditions and small depths of cut, helping to control chip shape and evacuation without disturbing the workpiece finish. The combination of the NS9530 grade and the DNMG form supports longer edge life in finishing tasks, reducing downtime for edge changes and promoting process stability in production runs.

FAQ

Which materials is this insert best suited for? The DNMG150412 NS9530 insert is a finishing-grade cermet optimised for steel; it performs best in continuous-turning operations and small depths of cut where surface quality is paramount.

How is the insert secured in the holder? Compatibility relies on ISO DNMG form and the holder design; the insert features a central cylindrical hole for positive location and clamping with the appropriate screw and seat to ensure stable cutting.

Can the insert be indexed to extend tool life? Yes, the double-sided design provides multiple usable edges; the insert can be rotated or flipped to use alternate cutting edges, supporting economical edge changes in production.

What surface finish can be expected with this grade? With the NS9530 cermet and a 1.2 mm corner radius, the insert is engineered to deliver a fine surface finish in finishing passes, reducing the need for additional finishing operations.

Is the insert suitable for internal as well as external turning? The ISO DNMG form and the sharp cermet edge make the insert suitable for both external and internal turning tasks, provided the correct holder and cutting parameters are used.
